ICategoryService

public interface ICategoryService
{
    public Category create(Category category);
    public Category delete(int id) throws Exception;
    public List findAll();
    public Category update(Category category) throws Exception;
    public Category findById(int id);
}

他的实施

public class CategoryService implements ICategoryService
{
    @Autowired
    private CategoryRepository categoryRepository;
...

调节器

@Controller
@RequestMapping(value = "/rest")
public class StorageController extends BaseController {
    @Autowired
    @Qualifier("categoryService")
    private ICategoryService _categoryService;
...

database.xml

beans.xml中

我的错误在哪里？

这是您的异常消息中的最后一个原因

Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException

Spring无法调用你的init方法,jpaMappingContext因为发生了持久性异常 - 数据库出了问题.

因此,Spring自动装配实际上正在工作,但由于初始化其中一个spring bean时出现数据库问题,因此无法自动连接您的依赖关系.

因此,自上次编码以来,数据库或数据库设置中的某些内容已更改.分析完整堆栈跟踪以找出此问题的根本原因 - 这是一个数据库问题.
